I purchased a dedicated dual xeon with 2 GB of ram. I have 4 server running on the box.

We have a 25 Man 100 tick 500 FPS pub, and for some reason at the beginning of every round the tick drops to 50, and will hover there until a couple people die or something, and then it will pop back to a constant 100..
The choke remains very low though..

This also happenes on my private 12 man sometimes as well, could this be a cfg error? or is it bc of the FPS being 500? any ideas?
